A low-key build system for working with data.
laforge is a low-key build system for working with data.
You know, I've always thought technology could solve almost any problem.
$ python -m pip install laforge -q ... $ laforge create Creating /home/matvan/science/build.ini ? Creating a new laforge INI at: /home/matvan/science/build.ini Creating /home/matvan/science/build.ini ? Default read directory, relative to /home/matvan/science/: ./data ? Default write directory, relative to /home/matvan/science/: ./output ? Default execute directory, relative to /home/matvan/science/: ./ ? SQL Distribution: SQLite ? Database: :memory: New laforge INI written at: /home/matvan/science/build.ini Enjoy!
There's theory and then there's application. They don't always jibe.
$ vim ./build.ini ... $ cat ./build.ini [DEFAULT] read_dir: ./data write_dir: ./output execute_dir: ./ distro: sqlite database: :memory: # Write the contents of an Excel sheet as a SQL table [load_individual] read: 2019_indiv_data.xlsx write: raw_grp # Write the contents of a CSV as a SQL table [load_group] read: 2019_grp_data.csv write: raw_indiv # Execute a standalone SQL script; read a SQL table and save as CSV [do_some_things] execute: do_stuff.sql read: laforge.demo.aggregate write: aggregate.csv # Read the result of an ad-hoc SQL query; write to an HTML table [peek] read: "select top 50 * from demo.aggregate agg left join demo.raw_indiv ri on agg.v1 = r1.v2 order by newid();" write: results_peek.html
Yeah, but that's imposs—yes, sir.
$ laforge build
Captain, we can do it... It'll take fifteen years and a research team of a hundred.
